Report No. c012

Wilhelmus de Cabriano



Alternative Names

Guillaume de Cabriano; Wilhelm von Cabriano; Guglielmo da Cabriano



From a family of high standing in Brescia. Probably a student of Bulgarus, not Placentinus, as earlier surmised. Probably a contemporary, not teacher, of Johannes Bassianus. Possibly the anonymous bishop of Asti (from 1173) who became archbishop of Ravenna in 1191, in which case he died in the summer of 1201. Not a jurist of great significance, although his Casus codicis would have served well to introduce students to the main issues of law. His glosses are cited only rarely in the Glossa ordinaria, but his views appear more often than some in the Dissensiones dominorum. His siglum is ‘W’.
